Two containers have a substantial amount of the air evacuated out of them so that the pressure inside is half the pressure at sea level. One container is in Denver at an altitude of about 6,000 ft and the other is in New Orleans (at sea level). The surface area of the container lid is A = 0.0085 m2. The air pressure in Denver is PD = 81000 Pa. and in New Orleans is PNO = 101500 Pa. Assume the lid is weightless.

Randomized Variables
A = 0.0085 m2
PD = 81000 Pa
PNO = 101500 Pa

Part (a) Write an expression for the force FNO required to remove the container lid in New Orleans.

Part (b) Calculate the force FNO required to lift off the container lid in New Orleans in N.

Part (c) Calculate the force FD required to lift off the container lid in Denver in N.

Part (d) Is more force required to lift the lid in Denver (higher altitude, lower pressure) or New Orleans (lower altitude, higher).
